Mesenchymal stem cells and bovine bone mineral in sinus lift procedures--an experimental study in sheep.

Introduction: New reconstructive and less invasive methods have been searched to optimize bone formation and osseointegration of dental implants in maxillary sinus augmentation.

Purpose: The aim of the presented ovine split-mouth study was to compare bovine bone mineral (BBM) alone and in combination with mesenchymal stem cells (MSCs) regarding their potential in sinus augmentation.

Material And Methods: Bilateral sinus floor augmentations were performed in six adult sheep.
